Kind Code:
B2
Abstract:
PURPOSE:To improve the retrieval accuracy and the retrieval designating expression capacity by designating a retrieval condition obtained by combining a regular expression, dictionary information and syntax information, and collating an input sentence and the retrieval condition, based on a result of morpheme analysis and a result of syntax analysis of the input sentence. CONSTITUTION:A natural language input sentence read into an input sentence reading-in part 1 is transferred to a morpheme analyzing part 2 through a communication line 12. The morpheme analyzing part 2 obtains dictionary information to an input sentence from a dictionary part 3 and executes a morpheme analysis, transfers a result of morpheme analysis to a retrieval condition collating part 5 and a syntax analyzing part 6, and the syntax analyzing part 6 executes a syntax analysis, and transfers a result of syntax analysis to the retrieval condition collating part 5. Also, a retrieval condition read into a retrieval condition designating part 4 is transferred to the retrieval condition collating part 5, and the retrieval condition collating part 5 collates the input sentence and the retrieval condition by using the result of morpheme analysis and the result of syntax analysis, and outputs them through a communication line 50 when the condition is satisfied. In such a way, the retrieval accuracy and the retrieval designating expression capacity can be improved.
